Premium Spicer Life Series® u-joints excel in performance and life. The journal crosses are cold-formed from high quality steel for maximum strength. Non-Greasable u-joints have Ample grease reservoirs in each trunion to assure effective lubrication and are pre-filled with high quality synthetic lithium grease providing superior friction reduction and higher temperature resistance. Spicer Life Series® u-joints use Spicer’s highest quality, triple-lip seal along with an external seal guard to resist the harshest conditions. So when you replace your car or truck universal joints with genuine Spicer technology, you can rest assured that you are helping to ensure the maximum life for your vehicle.
Non-Greasable u-joints are stronger than greaseable units since they don’t have any grease passages in them.
